System LSI designs • System LSI design = LSI chip design + Embedded software development • Very complicated tasks both as HW and SW • Should be reasoned about in very abstracted design levels – CAD supports for higher designs levels than RTL are essential • However, there are several hard but should-be-solved-quickly problems µProcessor Control IP Comp. Memory Pipeline RAM IF FSM IP Netlist State PC Interface IR Control Bus Interface Processors IPs Memories Busses Functional specification + constraints Interface Analog parts Memory Registers ALUs/FUs Memories Gates State Datapath Mem RF IF FSM Analog parts Memory State ALU Custom HW System architecture + estimates RTL/IS Implementation 4 + results
